In fourth grade, students expand their knowledge of place value, fractions, and measurement while developing greater fluency with the four operations. They learn to tell time, measure objects, and represent data more precisely. No doubt about it: fourth graders are busy! However, incorporating hands-on games and activities in the classroom is still a great way to reinforce these new concepts. In this article, we explain the typical standards for fourth-grade math, share important teaching strategies, and explore four fun activities students love.
What are the fourth-grade math standards?
While 4th-grade math standards vary by school, district, and state, they typically focus on five key areas: operations and algebraic thinking, number and operations in base 10, number and operations in fractions, measurement and data, and geometry.
Operations and Algebraic Thinking
In 4th grade math, students are expected to add and subtract multidigit numbers. Throughout the year, they also learn to multiply and divide by multidigit numbers and solve word problems using all four operations. Students will identify factor pairs and multiples of whole numbers up to 100 and learn to generate and analyze number patterns with a given rule.
Number and Operations in Base 10
Fourth grade continues to build on students’ understanding of the base 10 number system, which uses ten digits (0-9) to represent any number. Students use their place-value knowledge to round numbers to any place value and recognize that a digit in one place represents 10 times the place to the right. They also read and write whole numbers using numerals, number names, and expanded form.
Numbers and Operations- Fractions
Students understand that fractions represent parts of a whole and can represent them on a number line diagram. They can identify and explain equivalent fractions using a visual fraction model and recognize fractions that are equivalent to whole numbers. 4th graders compare fractions by using >, =, or < and explain their thinking. Students also learn to add and subtract fractions, multiply fractions by whole numbers, and express fractions as decimals.
Measurement and Data
In 4th grade, students learn to describe, compare, and classify measurable objects. They convert larger measurement units into smaller ones, such as hours to minutes or feet to inches, and record their findings in a table or graph. Students use the four operations to solve word problems involving distance, time, volume, mass, and money, and represent these quantities on a diagram. Fourth graders apply their knowledge of area and perimeter to real-world problems, and measure angles using a protractor.
Geometry
Fourth-grade students draw and identify points, lines, line segments, rays, angles, and perpendicular and parallel lines in two-dimensional figures. They also learn to identify and draw lines of symmetry and to fold the line to create matching parts. Fourth graders classify figures based on certain attributes, like the presence or absence of angles.
Tips for Teaching Fourth-Grade Math
Support Number Sense
Developing number sense remains essential in 4th grade, as students work with larger numbers and solve more complex problems. Students with strong number sense recognize patterns, estimate accurately, and choose effective strategies to find the correct answer. Activities that require flexible thinking, such as number talks, encourage students to use mental math and share their approaches with others.
Use “CRA” to Build Confidence
CRA, or the concrete-representational-abstract method, helps students transition from using physical objects to visual representations and ultimately to abstract reasoning to solve problems. Using this approach in 4th-grade math is important because it helps students develop conceptual understanding before moving on to abstract equations and procedures.
Connect Prior Knowledge
Fourth-grade math builds on skills learned in earlier grades. Understanding this gives students the confidence to tackle new concepts, so emphasize connections between familiar skills and new learning. For example, showing how multiplication relates to division or how fractions represent parts of a whole helps students develop a deeper understanding of mathematical relationships.
Differentiate Instruction
Differentiating instruction to meet the needs of all learners is essential in every grade. Fourth graders arrive with different levels of readiness. Some may need an extra challenge, while others need additional support. Providing multiple ways to practice skills and demonstrate understanding will help all students gain the skills and confidence they need.
Use Games to Reinforce Learning
Although 4th graders are shifting from concrete to abstract reasoning, hands-on games and interactive activities still allow students to practice meaningful skills while having fun. Board games, cards, online programs, or activities that incorporate movement motivate and excite 4th graders to learn.
Create a Positive Environment
A supportive classroom environment helps students feel safe taking risks and making mistakes. When students feel supported, they build confidence and positivity and become more curious about their learning. Celebrate progress over perfection by looking for opportunities to celebrate each student.
Assess and Reflect Regularly
Formative assessments give teachers important data to review student progress quickly and correct misunderstandings in real time. Also, asking students to reflect on their learning strengthens critical thinking skills. Examples of formative assessments for 4th graders include number talks, whiteboard quizzes, and exit tickets.
Teach Problem-Solving Strategies
Fourth graders benefit from explicit instruction in effective problem-solving strategies. For example, a teacher might explicitly model how to use the volume formula (V = l x w x h) by solving a problem aloud, step by step. The teacher then guides the students to draw a similar number line together before having them work independently.
Make Real World Connections
When students connect classroom math to real-world situations, they are more likely to find it meaningful and “worth their time.” By fourth grade, students are usually mature enough to take part in more adventurous, experiential activities that make learning fun.
Continue Developing Math Vocabulary
Fourth graders should already have foundational math vocabulary, and it’s important to continue building academic language throughout their math journey. Make sure students truly understand terms such as factor, multiple, numerator, denominator, and equivalent, and look for opportunities to use them in lessons.
Four Fun Fourth Grade Activities
Guess the Number
Think of a number and give students written or verbal clues, such as “the number is greater than 50 but less than 72,” or “the number cannot be divided in half evenly.” Students guess aloud until they find the mystery number. Working as a whole group is a great way to fill extra time with a purposeful, engaging activity.
Interactive Learning Platforms
Recent research has found that gamified learning tools can actually increase motivation among school-aged children. With that in mind, check out Dreambox Math, an online program perfect for parents, teachers, and students. With personalized support and plenty of interactive games, Dreambox is a great way to keep 4th graders excited about math!
Art with Arrays
Combining art and math allows students to express their creativity while strengthening their multiplication skills. Provide each student with a sheet of grid paper, a set of multiplication problems, and colorful markers or pencils. For each problem, students draw an array that matches the equation, such as a 2-by-6 rectangle for 2×6, and label it with the correct answer. This can also be done with multiplication word problems. As they solve each problem, they combine their arrays into a larger picture. Afterward, invite students to share their artwork with the class.
Crack the Code Challenge
In this activity, students solve a series of word problems to uncover clues that help them complete a mission. Before class begins, write individual word problems on index cards. Each correct answer reveals a number corresponding to one letter of the code. Place each card around the room (or outdoors, if you can) and give each student a notebook to track their progress. As they solve problems, they gather all the letters needed to unlock the secret code. This activity is highly adaptable and can be as simple or elaborate as time allows. Having one small group playing at a time, and perhaps delegating problems to specific students, allows everyone the opportunity to crack the code.
